In 2021, the Great Resignation gave way to the “Great Creation” as entrepreneurs across a wide swath of industries struck out to follow their passions, bringing about a startup renaissance like never before. That’s why SourceScrub is thrilled to announce our list of the most successful bootstrapped startups of the year!

To put this list together we scoured the universe of founder-owned businesses for promising young companies that have proven to be among the fastest-growing private companies in America, but are still unlikely to have shown up on dealmakers’ radars just yet. Using key company growth signals including employee, job posting, marketing, web, and investor data, we determined these companies are the ones to watch.

Unlike our list of the fastest growing startups of 2020, where the majority of the Top 10 was made up of medical companies, this year’s list highlights only one healthcare-centric brand. Instead, we see a diverse array of B2B industries representing everything from explainer videos to strategy creation.

It seems as though the market is transitioning from being all-consumed by the global pandemic to learning how to navigate the business world alongside it. The connective tissue between the companies on this year’s list appears to be an emphasis on doing better business in every sense of the word. For example, we’re watching as CustomerHD improves customer experiences, Analysis Prime builds client relationships, and Accentec Technologies provides the supplies businesses need to do it all.

We do see some outliers though. These include space travel-oriented Astra, consumer goods seller Congo Brands, and full-service mortgage provider Cornerstone First Mortgage. And with health and wellness still top of mind, it’s no surprise to see healthcare services provider Avidon Health, LLC rounding out our top 10.

Also of note is geographic location. Most of these companies take up residence in California, with a handful of Midwestern and Southern states also checking in. New Jersey steps up to represent the East Coast’s only contender for the year.

Our list started with nearly a million contenders from our private company database and was crafted using SourceScrub’s Custom Scoring capability, balancing a 12-month growth rate with company size measured by headcount. The result is an eclectic mix of emerging companies across a range of industries including gaming, insurance, analytics, logistics, healthcare, telecom, packaged goods, and more. Let’s dig into the top 10!
